Create New Geographies or Datasets

Datasets and geographies imported into SpaceStat can be modified in a variety of ways:

• A new geography can be created from a subset of an existing geography.  To do this, select areas in a map, then right-click and select the "New geography from Select" option.

• -> The representation of the objects can be changed from polygons to points using the "Create a centroid geography" option located under the Tools menu.

• ->, or ->  You can convert data from point datasets to polygon datasets, and from polygon datasets to polygon sets with a different geography.  

• You can standardize datasets using the Z-score transformation, or smooth them using either Poisson smoothing or the Empirical Bayesian smoother (Methods menu, Data transformation section of Help).

• New datasets can be created from existing datasets using the dataset calculator (Tools menu, "derive new dataset").

• New datasets can be also be created from existing datasets using statistical methods (Methods menu, Statistical Methods section of Help).

• New spatial weights sets can be defined for use in spatial statistics (right click on a geography in the spatial weights view).

• You can define new variogram models in the variogram model dialog to use in kriging (right click on a geography in the variogram model view).

New geographies or datasets created from others are nested by default, and placed underneath their parents in the datasets window.
